HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 353,354, dated November30, 1886,

Application filed March 24, 1886. Serial No. 196,352. (No model.)

To all whom it may concern:

Be it known that I, ISAAC Frame, of Boston, county'of Suffolk, and Stateof Massachusetts, have invented an Improvement in Home shoes, of whichthe following description, in connection with the accompanying drawings,is a specification, like letters on the drawings representing likeparts.

This invention has for its object to provide a horseshoe which may bereadily used as either a plain or a sharp or calk shoe, the addition ofthe sharp or calk part being quickly and easily made, the junction beingvery firm and secure.

In accordance with my invention I provide a plain shoe with a cross-barhaving a substantially central threaded hole, and near the toe the saidshoe is provided, preferably, with a hole, or it may be with a stud. Tothe outside of this plain shoe having the described additions I apply anauxiliary shoe, preferably made as a plate having calks, thesaid plate,as herein shown, having a stud to enter the hole in the toe of the shoe,a central slot in the said plate receiving through it a bolt, thethreaded part of the bolt being screwed into a threaded hole in thecross-bar of the main shoe nailed to the hoof.

Figure 1 represents the main shoe; Fig. 2, the auxiliary shoe, or sharpor calk part. Fig. 3 shows the auxiliary shoe applied to the main shoe,and Fig. 4 a section of Fig. 3 in the dotted line a; x.

The main shoe a, having usual nail-holes, a, is provided with across-bar, a having a threaded hole, 06. The shoe a, near the toe part,also has a hole, of, or it might be a stud, the converse of the hole.

The shoe so far described is a plain shoe, and is suitable for roads notcovered with snow or ice. I

The auxiliary shoe, as herein shown, is composed of a plate, b, of asize and shape to cover, preferably, the open space of the shoe a. Thisplate 12 has a toe-calk, b, and two heelcalks, b", and if the shoe a hasa hole at a" then the plate I) will have a stud, 72 to enter the saidhole. The plate 6 is slotted at If to receive a bolt, b which, screwedinto the threaded hole in the bar (1, serves to confine the auxiliaryshoe or sharp or call: part in place on the main shoe. The slot 1)permits the plate b to be adj usted to place the calks b I)" in anydesired position with relation to the heel of the shoe a or the hoof ofthe'horse, for it frequently happens that the heel calks have to beadjusted in position to the pecu liarities of gait of the horse to whichthe shoe is applied. The application of the plate b to or its removalfrom the shoe may be made very quickly, as occasion requires.

It will be noticed in my improved shoe that the sharp or calk part isapplied directly to the outside of the main shoe, and that ittakesbearing on the bottom of the main shoe, and that it may be made verythin and light.

I do not desire to limit my invention to making the calks as integralparts of the plate I). for they may be separately attached to the plateI) by welding, or by other usual ways.

To avoid the possibility of the plate slipping under the head of thebolt, I may plug the ends of the slot each side the bolt with pieces ofleather, as at c in black; or, if de sired, I may use more than oneset-screw.

I claim 1. The main shoe having a crossbar, a, provided with ascrew-threaded hole, and the auxiliary'shoe having calks, and slottedand provided with an opening for the reception of a bolt, combined witha bolt to attach the said main and auxiliary shoes together,substantially as described.

2. The main shoe a, having a cross-bar. a", provided with ascrew-threaded hole, the said shoe also having a hole for the receptionof a stud,and an auxiliary shoeprovided with cal ks and with a stud andwith a slot for the reception of a bolt-,-combined with a bolt to connect the said main and auxiliary shoe, the stud of one shoe entering ahole in the other shoe, the slot and bolt permitting adjustmentof theauxiliary shoe on the main shoe, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ISAAC FENNO.
